cout<<endl<<"ENTER MARKS"<<endl<<endl<<"English: "<<endl;
cin>> eng;
cout<<"Mathematics: "<<endl;
cin>>math;
cout<<"Dhivehi: "<<endl;
cin>>dhiv;
cout<<"Islam: "<<endl;
cin>>islam;
cout<<"Science: "<<endl;
cin>>sci;
tot = eng+math+dhiv+islam+sci;
avg = tot/5;
cout<<endl<<"Total Marks = "<<tot<<endl;
cout<<endl<<"Average Marks = "<<avg<<endl;
if (avg>=75)
grade = 'A';
else if (avg>=65 && avg<=74)
grade = 'B';
else if (avg>=50 && avg<=64)
grade = 'C';
else if (avg>=40 && avg<=49)
grade = 'D';
else
grade = 'F';
cout<<endl<<"Grade = "<<grade;
